Homework Answers
Phenylketonuria is an autosomal recessive disease. This means one has to have both alleles recessive for a mutated phenylalanine hydroxylase protein in order to be affected by the disease. In the given situation, the parents do not have the condition but their child does.This means they are surely carriers or heterozygous in their genotypes for a mutated phenylalanine hydroxylase protein.
Value 1 : As discussed above the suitable answer is option C.
For the next question also marked as Value 1 : Ginny and Harry are both heterozygous. So the probability of their offspring getting only one affected gene should be 50%. Thus option C is the correct answer here.

5. (30 0 points) Phenylketonuria (fen-ul-ke-toe-NU-re-uh), also called PKU, is a rare inherited disorder that causes an amino acid called phenylalanine to build up in your body. PKU is caused by a defect in the gene that helps create the enzyme needed to break down phenylalanine. Without the enzyme necessary to process phenylalanine, a dangerous buildup can develop when a person with PKU eats foods that are high in protein. This can eventually lead to serious health problems. For the...

Betsy has an autosomal recessive disorder. Kevin is a carrier.
They have one boy (II-3) who has the same autosomal recessive
disorder as his mom.
On the gel, thick bands represent twice as much DNA as thin
bands (kb = kilobases = length). Betsy is homozygous for the 4-kb
mutant allele. Kevin is heterozygous for the 4-kb mutant allele and
the 15-kb normal allele.
Which of the following situations could explain the genotype of
their first son (II-2)?
